To this end, the oral care implement 1 is dense, and the oral care agent held by the applicator 400 is well preserved when the applicator 400 is in a stored state.

In a variation of the illustrated embodiment, an elastomeric seal such as an O-ring The cover may be disposed on the body 100 or on the cover 300. When the cover 300 is in the first position relative to the body 100, the elastic seal is positioned around the opening 130 and compressed between the body 100 and the cover 300. Thereby, it is better ensured that the oral cavity which is held by the cavity 114, the applicator 400 and the applicator 400 is isolated from the outside of the toothbrush 1. Preferably, the elastomeric seal provides cavity 114 with water tightness and/or air tightness. The elastomeric seal may be partially molded into the material of the body 100 or cover 300, respectively, during manufacture of the toothbrush 1, or may be attached thereto, such as by an adhesive.

When a user wishes to use the applicator 400, it moves the cover 300 from the first position relative to the body 100 to the second position shown in Figures 2 and 3. More specifically, the cover 300 is first decoupled from the body 100 by pulling the cover 300 away from one of the bodies 100 by a force sufficient to decouple the projection 115 from the recess 315, which then continues to cap 300 Moving relative to the body 100 to the second position, the applicator 400 becomes stretched between the body 100 and the cover 300 and placed in fluid communication with the exterior of the toothbrush 1. When the cover 300 reaches the second position relative to the body 100, the applicator 400 is exposed in an applied state. Applicator 400 extends from cavity 114 through opening 113 when cover 300 is in the second position relative to body 100. In the illustrated embodiment, when the cover 300 is in the second position relative to the body 100, the distance between the cover 300 and the body 100 ("second distance,") is between 5 and 15 cm, preferably Between 8 and 15 centimeters, and most preferably between 10 and 15 centimeters. To this end, a typical user is capable of rubbing the applicator 400 onto its teeth and/or gums and/or tongue, thereby applying the applicator 400 holds the oral health care agent applied to the teeth and/or gums and/or tongue. After applying the oral care agent held by the applicator 400 to the oral surface thereof, the user then causes the cover 300 to be relative to the body The 100 moves from the second position to the first position to allow the applicator 400 to contract and retract into the cavity 114 and to press the cover 300 in the direction of the body 100 by aligning the projection 115 with the projection 115 to cover the cover 300 is coupled to the body 100 such that the tab is "snapped" into the recess 315 and the applicator 400 is placed back into the stored condition.

For this reason, the applicator of the toothbrush 1 can be conveniently used to put an oral health care agent Apply to an oral surface. The appliance 1 can be reused multiple times to apply the oral care agent to an oral surface.

In variations of the illustrated embodiment, the cavity 114 can be disposed at other locations in the body 100 that are not shown. For example, the cavity 114 can be disposed in the handle 110 away from the proximal end 111 of the handle 110, such as in or adjacent to the neck portion 118 of the handle 110. In a partial variation of the illustrated embodiment, the handle 110 can define an opening 113 that is remote from the cavity 114 of the proximal end 111 of the handle 110, such as in or adjacent to the neck portion 118 of the handle 110 or a handle. At the distal end 112 of 110. In variations of the illustrated embodiment, the cavity can be located in the head 120 of the body 100, and the head 120 can define an opening in the cavity. In a partial variation of the illustrated embodiment, the cavity can be located in both the handle 110 and the head 120 of the body 100. An opening into such a cavity located in both the handle 110 and the head 120 can be defined by the handle 110 or by the head 120. In some embodiments, a plurality of cavities can be disposed in the body 100, and the respective openings of the cavities can be defined by the handle 110 and/or by the head 120.

In variations of the illustrated embodiment, the cavity 114 can be disposed in the cover 300 rather than in the body 100. In such variations, the cover 300 will define an opening in the cavity, and when the cover 300 is in the first position relative to the body 100, the body 100 can block the opening.

In a partial variation of the illustrated embodiment, the cover 300 can be unitary with the body 100. For example, the cover 300 can be coupled to the body 100 by a living hinge. However, the cover 300 can still be used to block the opening 113 defined by the body 100, and the cover 300 will still be movable relative to the body 100 from a first position to a second position to condition the state of the applicator 400 from one. The state changes to an applied state.
